    Hey PowerBI123456 ,

    here you will find a new approach :-), be aware that this approach is referencing the columns from your dimension tables. For this it's also necessary to change the visuals as well. Meaning: use columns from the dimension tables instead.
    This measure is also not that generic, as it returns the max requestID, so it will return the expected results whenever the acoount colum is used.
    If you use the measure on a card visual it will retrun 12 instead of 4. If you need the 4 I recommend using a SUMX or COUNTX in combination with VALUES('...'[account]  

    MaxReq Star = 
var t = 
ADDCOLUMNS(
        VALUES( 'DIM: Accounts'[Account] )
        , "maxrequestid" 
            , var MaxResponseID =
                CALCULATE( 
                    MAX( 'FACT: Activity'[ID] )
                    , ALL('DIM: Date' )
                    , ALL( 'DIM: Users' )
                    , ALL( 'FACT: Activity'[ID] )             
                    , 'DIM: Activity'[Activity] = "Response"
                )
            var MaxRequestID = 
                CALCULATE( 
                    MAX( 'FACT: Activity'[ID] )
                    , ALL( 'DIM: Date' )
                    , ALL( 'DIM: Users' )
                    , 'DIM: Activity'[Activity] = "Request"
                    
                    --, 'FACT: Activity'[ID] = MaxResponseID - 1
                    , 'FACT: Activity'[ID] < MaxResponseID
                )
            return
            MaxRequestID
        )
return

CALCULATE(
    MAX( 'FACT: Activity'[ID] )
    , TREATAS( t , 'DIM: Accounts'[Account] , 'FACT: Activity'[ID] )
)

    Here is a screen shot that shows the column usage of the tree map visual:

    Be aware that the overall challenge we are facing is based on the fact that the datastore (our beloved SSAS Tabular inside Power BI) does not know a sequence data type. Sometimes, here, this makes things hard, the other times it's a plus.

    Nevertheless, if this does not work, you might want to read this article, here I present a different approach to tackle the previous value challenge: The previous value - Mincing Data - Gain Insight from Data (minceddata.info)

TomMartens Hi - I am trying to show the users who put in the last request. Based on the data, it would be:

  • Account 1: John
  • Account 2: Will
  • Account 3: Amber
  • Account 4: John

I want to use a treemap to show that each of those 4 people had 1 request. The problem is my current treemap is counting everyone that made a request for each account, so its showing more than I want. Hope that makes sense.

Hey PowerBI123456 ,

 

this measure

MaxReq = 
var t = 
    ADDCOLUMNS(
        FILTER(
            'Activity'
            , CALCULATE(
                CONTAINSROW(
                    VALUES( 'Activity'[Activity] ) 
                    , "Response" 
                ) 
                , ALLEXCEPT( 'Activity' , Activity[Account] )
            )
        )
        , "MaxRequestID"
            , var account = [Account] 
            var maxID =
                CALCULATE( 
                    MAX( Activity[ID] ) 
                    , ALL( 'Activity' )
                    , 'Activity'[Account] = account
                    , 'Activity'[Activity] = "Request"
                )
            return
            maxID
    )
return

SUMX(
    t 
    , IF(
        'Activity'[ID] = [MaxRequestID] && 'Activity'[Activity] = "Request"
        , 1 --[MaxRequestID]
        , BLANK()
    )
)

allows to create this report page

From a data visualization point of view I favor the stacked bar much more then the Tree map.

If "just" want to show the user who is in charge for the last request, I would use a simple table Account | User | the measure [MaxReQ]
I'm not sure if I really understand the date stuff from your measure, maybe you have to check my measure with a larger dataset.

 

Hopefully, this is what you are looking for.

Regards,
Tom
